.WARP-STOP-MOTION ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filed April 14, 1913. Serial No. 760,884.

To I/Zl 'Ie/mm if may concern Be'it known that I, Gnoncn Pa'r'rnnson, a citizen of the United States, residing at hianchcstcr, county of Ilillsboro, and State of New IIampshire, have invented an Improvement in lVarp-Stop-lviotion Attaclr meats oi which the following description,

in connection with-the accompanying drawings, is a specification, like letters on'the drawings representing like parts.

The invention to be hereinafter described drop wires or warp detectors, or in working upon other Features; and occasion sometimes arises while the o 'ierativc is thus enga ed to stop the loom quickly withouttaking time to pass through the alley-ways to reach the shipper at the front of the loom.

With these facts in mind the aims and purposes of the present invention are to provide simple and convenient means, act-- ing through parts of the warp stop motion, which will enable the operative to quickly stop the loom withoutthe necessity of pass ing around the structure to reach the shipper, all of which will best be made clear from the following description and accom panying drawings of one convenient form of means for carrying the invention into practical etiect it being understood, of course, that the invention is not limited to such particular means, but is set forth in its true scope by the claims.

in the drawings: Figure 1 is a central vertical section from front to rear of sutlicientof a loom and warp stop motion to make clear the character and operation of the present invention; and Fig. 2 is an enlarged detail at the rear of the loom showing port ons of the warp stop motion and the association therewith of a device embodying a. convenient form of the invention.

The loom may be of any Well-known or desired character having a warp stop motion, and as typified in the drawing, it comprises a frame 1, the usual lay 2, said parts being operated as usual from any desired source of power. These parts as well as the whip-roll or warp guide 6 need no further detailed description, as they are wellknown and familiar to those skilled in the art. Rising from the loo-m frame 1 are the brackets 7,- one at each side of the loom, which serve as supports for a warp stop motion.

In the form of the invention illustrated, the warp stop motion comprises a series of drop devices or warp detectors 8 which may be arranged in two transverse rows, as shown, each drop device or detector having a guiding slot 9 through which pass one of the guide rods 10. Each drop device or detector has also an eye 11 for the passage of a warp thread 12, whereby,'the drop devices or detectors are normally held out ofthe path ried by a rock shaft 1 through the arms 15, Fig. 2. This vibrator or feeler 13 may be of usual character and be given. its rockin or feeler movement by the rods 16 or ot ier suitable. means common in this class of devices, the construction being such that should the fceler or vibrator be obstructed in its movement by a drop device or detector due to a broken or abnormally slack warp thread, the shipper 17 will be dislodged from its holding notch, and the loom be brought to rest. As hereinbefore noted the feeler, as well as the drop devices or detectors 8, and the means between the feeler and the shipper 17 for throwing the shipper from its holding notch when the feeler movement is obstructed may be of any approved -form and construction, and being well known and familiar to those skilled in the art further illustration and description thereof will be unnecessary.

In the form of the device illustrated, see Fig. 2, the brackets 7 have secured thereto the depending brackets or arms 18 to which are secured by means of screws 20 orotherwise, the side bars or rails-19, 19 of the warp stop motion. The guide rods 10 which pass through the drop devices or detectors 8, may likewise be secured in guiding position onthe depending brackets 18 by suitable means, such as thebolts 21 passing into lugs 22 projecting from the brackets 8. While these details are found to be convenient form of a vibrator or feeler 13 carof means for the purpose stated, it will be understood of course, that such details are notessential and may be varied.

In Waip stop motions of this general charactor, where a vibrating feeler is employed, it is common when movement of the feeler 13 is obstructed to detach the shipper from its holding notch and cause loom stoppage, and the present invention takes advantage of this fact and provides means which may be conveniently operated by the loom tender, when at the rear of the loom or at points from which the shipper cannot be reached, to quickly act through the Warp stop motion to stop the loom. As one convenient form of means to this end, the present invention contemplates a finger normally inoperatively related to the warp stop motion, and which may be readily moved into operative relation therewith and act therethrough to quickly stop the loom. One form of such finger is indicated by the drawings, wherein 23 is a rod extending through a hearing 24 of an arm 25 which may be secured in position and to the loom frame by suitable means, such as the bolt 26 whichserves to also secure the. dep nding bracket is to the brackets 7, as indicated in Fig. 2. ()bviously the arm 25 for the rod 23 may be otherwise secured in position. it its upper end the rod 23 may be provided with a hand or finger-piece 27 and between it and the bearin' 24: is a spring 28 which normally acts to hold the lower end of the rod 23 out. of the path of the t'eeler L3, sul'istantially as indicatedin Fig. 2. arm is preferably so located with respect to the warp stop motion, that the lower end of the rod 253 may extend downward about centrally bet ween the sidebars or rails 1.!) so that upon depression lLllLifQO'f into the-path of the vibrator, it will act quickly upon the vibrator to arrest it in either direction of its;

movement, but, while this is a good and convenient disposition and i'elal 1011 or the parts, such relation may be varied within the true scope of the invention defined by the claims From the construction described, it will be noted that the rod 23, which for identifiea tion may be known as the manual stop tin- 'er, is disposed at the rear part, of the loom in convenient position to be reached by the The the rear of the loom for engagement by the attendant and adapted to be moved into the path of and to arrest movement of the feeler.

In a loom, the combination of a warp stop motion eoi'uprising a. vibrating feeler, a series of drop devices normally held out of the path of the teeler, and adapted to arrestinovemtnt of the feeler upon abnormal-condition of a warp thread, and a finger pr0- jecting; at the rear of the loom for manual operation by the attendant and adapted to arrest mm ement of the feeler during normal condition of the warp threads.

3. In a loom, the combination of a warp stop motion, a linger extendinf at the rear of the loom in position to be engaged by the attendant and mounted ior eofiperation. therewith, means for normally maintaining said finger in inoperative positionand permitting it to be manually moved into operative position to stop the loom through the warp stop motion.

i. in, a loom, the combination of a warp stop motion, a finger, means for .tnpporting the finger in. position. adjacent the warp stop motion, and in position to be engaged and operated by the loom lender, and a spring for holding the'iinger normally in inoperative position and permitting it to be moved into operative position by the loom tender to cause the warp stop motion to operate to s op the loom.

5. in a loom, a. warp st p motion comprisin; drop devices and a vibrating fceler for stopping the loom on the occurrence of a. tarp fault, a manually operable linger extending from a point adjacent the. warp stop motion for engagement by the attendant at the rear of the loom, a, guide tor directiing, movement of the finger toward and from the path oi the feeler, and means for normally maintaining the finger out oi the path of the feeler and permitting it to be manually movedhy the attendant at the rear of the loom into the path of the feeler to cause loom stoppage in the absence of a. warp fault.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
